Miniature rose plant &#39;POULdata&#39;

ABSTRACT

A new miniature rose plant which has abundant, non-fading, pink flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

SUMMARY OF THE INVENTION

[0001] The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between an unnamed seedling and ‘POULhappy’. The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULdata’. The new rose may be distinguished from its seed parent, an unnamed seedling, by the following combination of characteristics:

[0002] 1. The unnamed seedling is a pink miniature with bigger flowers than ‘POULdata’.

[0003] The new variety may be distinguished from its pollen parent, ‘POULhappy’, a rose variety with U.S. Pat. No. Plant 9,483 issued on Mar. 26,1996, created by the same inventors, by the following combination of characteristics:

[0004] 1. ‘POULhappy’'s flowers are orange-red, where those of ‘POULdata’ are pink.

[0005] 2. The flowers of ‘POULhappy’ are smaller thaan those of ‘POULdata’.

[0006] 3. ‘POuLhappy’ is shorter in habit than ‘POULdata’.

[0007] The objective of the hybridization of this rose variety for commercial culture was to create a new and distinct variety with unique qualities, such as:

[0008] 1. Uniform and abundant flowers;

[0009] 2. Vigorous and compact growth;

[0010] 3. Year-round flowering under glasshouse conditions;

[0011] 4. Suitability for production from softwood cuttings in pots;

[0012] 5. Durable flowers and foliage which make a variety suitable for distribution in the floral industry.

[0013] The combination of qualities of this variety represents significant improvement over previously available commercial cultivars of this type and distinguishes ‘POULdata’ from all other varieties of which we are aware. As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

[0014] ‘POULdata’ was selected by the inventors as a single plant from the progeny of the hybridization in Fredensborg, Denmark, in Spring, 1996. Asexual reproduction of ‘POULdata’ by cuttings and traditional budding was first done by L. Pernille and Mogens N. Olesen in Fredensborg, Denmark in July of 1996. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULdata’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

[0022] The following is a description of ‘POULdata’, as observed in its growth in glasshouses in Half Moon Bay, California, on plants aged sixteen weeks. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used. For a comparison, several physical characteristics of the rose variety ‘POULeden’, a miniature rose variety from the same inventors described and illustrated in U.S. Plant patent application Ser. No. 09/113,420 dated Jul., 10,1998 are compared to ‘POULdata’ in Chart 1.
